Derivative of xlnx | ln(3*x^2) on TI-89 | Every Step Calculus Video

This is a video from everystepcalculus.com demonstrating how my programs work on the TI 89 titanium calculator and other calculators in the TI system for calculus and physics problems. Okay derivative of natural log. Let’s get started to get to my menu at the press alpha and to put the letters i n d e x here in the main entry line of the calculator. and press alpha to put the eight me open close parentheses press enter in your menu we want a scroll down to natural logarithm and i want to differentiate yet the press alpha before you enter anything into these in these entry lines in programs. Don’t forget that. And we’re going to alpha log of three times x squared. We show you what you’ve entered, you can change it if you made a mistake. I say it’s okay. And here’s the calculation log of 3x squared. The formula is U prime over U. U being what’s inside the parentheses here. And then the derivative of that is 6x and when you put U prime over U. It equates out to 2 over x. Pretty neat, huh? everystepcalculus.com. Go to my site, buy my programs and pass calculus.
